Maybe be more alliterative and title it Tomasulo's Algorithm Considered Tempting? Because as far as I have found without reading original documents, its development and use in the IBM System 360/Models 91 and 95 was only but fully out-of-order on the floating point engine, they didn't have the gates, implemented with discrete transistors, to go further to speculative, or include any scalar hardware.
Hitting diminishing returns on caches with an ever increasing gate budget is I believe prompted this second generation starting in the 1990s which adds speculative execution, which the algorithm with all those extra hidden registers really invites you to do.
